The equation \( y = 3x^2 + 2 \) is a quadratic equation. Let's analyze its properties:
- Type: This equation is nonlinear because it includes a squared term, \( x^2 \).
- Function: It is a function because for every input \( x \), there is exactly one output \( y \). A function is defined as a relation where each input corresponds to one output.
Therefore, the correct classification for the equation \( y = 3x^2 + 2 \) is:
Nonlinear, function.
